Ilya Sutskever – We're moving from the age of scaling to the age of research

Speaker 1 You know what's crazy? That all of this is real.

Speaker 1 Yeah, meaning what? Don't you think so? Meaning what?

Speaker 2 Like all this AI stuff and all this Bay Area. Yeah, that it's happened.
Like,

Speaker 2 isn't it straight out of science fiction? Yeah.

Speaker 1 Another thing that's crazy is like how normal the slow takeoff feels.

Speaker 1 The idea that we'd be investing 1% of GDP in AI, like I feel like it would have felt like a bigger deal, you know, where right now it just feels like.

Speaker 2 We get used to things pretty fast, turns out, yeah. But also it's kind of like it's abstract like what does it mean

Speaker 2 what it means that you see it in the news yeah that such and such company announced such and such dollar amount right

Speaker 2 that's that's all you see right

Speaker 1 it's not really felt in any other way so far no should we actually begin here i think this is an interesting discussion sure i think your point about well from the average person's point of view

Speaker 1 nothing is that different will continue being true even into the singularity no i don't think so okay interesting So the thing which I was referring to, not feeling different,

Speaker 2 is, okay, so such and such company announced some difficult to comprehend dollar amount of investment. Right.
I don't think anyone knows what to do with that. Yeah.

Speaker 2 But I think that the impact of AI is going to be felt. AI is going to be diffused through the economy.
There are very strong economic forces for this.

Speaker 2 And I think the impact is going to be felt very strongly.

Speaker 1 When do you expect that impact? I think the models seem smarter than their economic impact would imply.

Speaker 1 Yeah,

Speaker 2 this is

Speaker 2 one of the very confusing things about the models right now. How to reconcile

Speaker 2 the fact

Speaker 2 that they are doing so well on evals.

Speaker 2 And you look at the evals and you go, those are pretty hard evals.

Speaker 2 They're doing so well.

Speaker 2 But

Speaker 2 the economic impact seems to be dramatically behind. And it's almost like

Speaker 2 it's very difficult to make sense of how can the model, on the one hand, do these amazing things. And then on the other hand, like repeat itself twice in some situation in a kind of a...

Speaker 2 An example would be, let's say you use wipe coding to do something.

Speaker 2 And you go to some place and then you get a bug. And then you tell the model, can you please fix the bug?

Speaker 2 And the model says, Oh my god, you're so right. I have a bug.
Let me go fix that. And it introduces a second bug.

Speaker 2 And then you tell it, you have this new second bug. And it tells you, oh my God, how could I have done it? You're so right again.

Speaker 2 And brings back the first bug. And you can alternate between those.

Speaker 2 And it's like, how is that possible? Yeah. It's like,

Speaker 2 I'm not sure. But it does suggest that the

Speaker 2 something strange is going on. I have two possible explanations.
So here, this is the more kind kind of a

Speaker 2 whimsical explanation: is that maybe RL training makes the models a little bit too single-minded and narrowly focused, a little bit too,

Speaker 2 I don't know, unaware,

Speaker 2 even though it also makes them aware in some other ways.

Speaker 2 And because of this, they can't do basic things. But there is another explanation, which is

Speaker 2 back when people were doing pre-training,

Speaker 2 the question of what data to train on was answered because that answer was everything.

Speaker 2 When you do pre-training, you need all the data.

Speaker 2 So you don't have to think, is it going to be this data or that data?

Speaker 2 But when people do RL training, they do need to think. They say, okay, we want to have this kind of RL training for this thing and that kind of RL training for that thing.

Speaker 2 And from what I hear, all the companies have teams that just produce new RL environments and just add it to the training mix. And then the question is, well, what are those?

Speaker 2 There are so many degrees of freedom. There is such a huge variety of RL environments you could produce.
And one of the

Speaker 2 one thing you could do, and I think that's something that is done inadvertently, is that people take inspiration from the evals.

Speaker 2 You say, hey, I would love our model to do really well when we release it. I want the evals to look great.

Speaker 2 What would be RL training that could help on this task, right?

Speaker 2 I think that is something that happens and I think it could explain a lot of what's going on.

Speaker 2 If you combine this with generalization of the models actually being inadequate, that has the potential to explain a lot of what we are seeing, this disconnect between eval performance and actual real-world performance, which is something that we don't today exactly even understand

Speaker 2 what we mean by that.

Speaker 1 I like this idea that the real reward hacking is the human researchers who are too focused on the evals.

Speaker 1 I think there's two ways to understand or to try to think about what you have just pointed out.

Speaker 1 One is, look, if it's the case that simply by becoming superhuman at a coding competition, a model will not automatically become more tasteful

Speaker 1 and exercise better judgment about how to improve your code base.

Speaker 1 Well, then you should expand the suite of environments such that you're not just testing it on having the best performance in a coding competition, it should also be able to make the best kind of application for X thing or Y thing or Z thing.

Speaker 1 And another, maybe this is what you're hinting at, is to say, why should it be the case in the first place that

Speaker 1 becoming superhuman at coding competitions doesn't make you a more tasteful programmer more generally?

Speaker 1 Maybe the thing to do is not to keep stacking up the amount of environments and the diversity of environments to figure out an approach which lets you learn from one environment and improve your performance on something else.

Speaker 2 So

Speaker 2 I have a human analogy which might be helpful.

Speaker 2 So even the case, let's take the case of competitive programming since you mentioned that. And suppose you have two students.

Speaker 2 One of them

Speaker 2 decided they want to be the best competitive programmer, so they will practice 10,000 hours for that domain.

Speaker 2 They will solve all the the problems, memorize all the proof techniques, and be very, very, you know,

Speaker 2 be very skilled at quickly and correctly implementing all the algorithms. And by doing so, they became the best, one of the best.

Speaker 2 Student number two thought, oh, competitive programming in school, maybe they practiced for 100 hours, much, much less, and they also did really well.

Speaker 2 Which one do you think is going to do better in their career later on?

Speaker 1 The second. Right?

Speaker 2 And I think that's basically what's going on. The models are much more like the first student, but even more, because then we say, okay, so the model should be good with competitive programming.

Speaker 2 So let's get every single competitive programming problem ever.

Speaker 2 And then let's do some data augmentation. So we have even more competitive programming problems.
Yes. And we train on that.
And so now you've got this great competitive programmer.

Speaker 2 And with this analogy, I think it's more intuitive.

Speaker 2 I think it's more intuitive with this analogy that, yeah, okay, so If it's so well trained, okay, it's like all the different algorithms and all the different proof techniques are like right right at its fingertips.

Speaker 2 And it's more intuitive that with this level of preparation, it would not necessarily generalize to other things.

Speaker 1 But then what is the analogy for what the second student is doing before they do the hundred hours of fine-tuning?

Speaker 2 I think it's like

Speaker 2 they have it.

Speaker 2 I think it's the it factor. Yeah.
Right. And like I know, like when I was an undergrad, I remember there was, there was a student like this that studied with me.
So I know it exists.

Speaker 1 I think it's interesting to distinguish it from whatever pre-training does.

Speaker 1 So one way to understand what you just said about we don't have to choose the data in pre-training is to say, actually, it's not dissimilar to the 10,000 hours of practice.

Speaker 1 It's just that you get that 10,000 hours of practice for free because it's already somewhere in the pre-training distribution.

Speaker 1 But it's like, maybe you're suggesting actually there's actually not that much generalization of pre-training. There's just so much data in pre-training.

Speaker 1 But it's like, it's not necessarily generalizing better than RL.

Speaker 2 Like the main main strength of pre-training is that there is A, so much of it. Yeah.

Speaker 2 And B,

Speaker 2 you don't have to think hard about what data to put into pre-training.

Speaker 2 And it's a very kind of natural data, and it does include in it a lot of what people do,

Speaker 2 people's thoughts, and a lot of the features of, you know, it's like the whole world as projected by people onto text.

Speaker 2 And pre-training tries to capture that using a huge amount of data.

Speaker 2 Pre-training is very difficult to reason about because it's so hard to understand the manner in which the model relies on pre-training data.

Speaker 2 And whenever the model makes a mistake, could it be because something by chance is not as supported by the pre-training data? You know, and pre-support by pre-training is maybe a loose term.

Speaker 2 i i don't know if i can add anything more useful on this but

Speaker 2 i don't think there is a human analog to pre-training

Speaker 1 here's analogies that people have proposed for what the human analogy to pre-training is and i'm curious to get your thoughts on why they're potentially wrong one is to think about the first 18 or 15 or 13 years of a person's life when they aren't necessarily economically productive, but they are doing something that is

Speaker 1 making them understand the world better and so forth. And the other is to think about evolution as doing some kind of search for three billion years, which then results in a human lifetime instance.

Speaker 1 And then I'm curious if you think either of these are actually analogous to pre-training, or how would you think about at least what lifetime human learning is like, if not pre-training?

Speaker 2 I think there are some similarities between both of these to pre-training, and pre-training tries to play the role of both of these. But I think there are some big differences as well.

Speaker 2 The amount of pre-training data is

Speaker 2 very, very staggering. Yes.

Speaker 2 And somehow a human being, after even 15 years, with a tiny fraction of that pre-training data, they know much less.

Speaker 2 But whatever they do know, they know much more deeply, somehow. And the mistakes, like,

Speaker 2 Like already at that age, you would not make mistakes that RAIs make.

Speaker 2 There is another thing. You might say, could it be something like evolution? And the answer is maybe, but in this case, I think evolution might actually have an edge.
Like, there is this, I remember

Speaker 2 reading about this case where some, you know, that one thing that neuroscientists do,

Speaker 2 or rather, one way in which neuroscientists can learn about the brain, is by studying people with brain damage to different parts of the brain.

Speaker 2 And so, and some people have the most strange symptoms you could imagine. It's actually actually really, really interesting.
And there was one case that comes to mind that's relevant.

Speaker 2 I read about this person

Speaker 2 who had some kind of brain damage that took out, I think, a stroke or an accident that took out his emotional processing. So he stopped feeling any emotion.

Speaker 2 And

Speaker 2 as a result of that, you know, he still remained very articulate and he could solve little puzzles and on tests he seemed to be be just fine.

Speaker 2 But he felt no emotion, he didn't feel sad, he didn't feel angry, he didn't feel animated, and he became somehow extremely bad at making any decisions at all.

Speaker 2 It would take him hours to decide on which socks to wear, and he would make very bad financial decisions.

Speaker 2 And that's very

Speaker 2 about

Speaker 2 the role of our built-in emotions in making us like a viable agent, essentially. And I guess to connect to your question about pre-training, it's like

Speaker 2 maybe

Speaker 2 if you are good enough at getting everything out of pre-training,

Speaker 2 you could get that as well. But that's the kind of thing which seems,

Speaker 2 well, it may or may not be possible to get that from pre-training.

Speaker 1 What is

Speaker 1 that?

Speaker 1 Clearly, not just directly emotion. It seems like some

Speaker 1 almost value function-like thing, which is giving telling you which decision to be made, like what the end reward for any decision should be. And you think that doesn't sort of implicitly come from.

Speaker 2 I think it could. I'm just saying

Speaker 2 it's not 100% obvious. Yeah.

Speaker 1 But what is that? Like, how do you think about emotions? What is the ML analogy for emotions?

Speaker 2 It should be some kind of a value function thing. Yeah.
But I don't think there is a great ML analogy because right now value functions don't play a very prominent role in the things people do.

Speaker 1 It might be worth defining for the audience what a value function is if you want to do that.

Speaker 2 I mean, certainly. I'll be very happy to do that.
Right.

Speaker 2 So

Speaker 2 when people do reinforcement learning, the way reinforcement learning is done right now,

Speaker 2 how do people train those agents?

Speaker 2 So you have a neural net and you give it a problem, and then you you tell the model go solve it. And the model takes maybe thousands, hundreds of thousands of actions

Speaker 2 or thoughts or something and then it produces a solution. The solution is created.
And then the score

Speaker 2 is used to provide a training signal for every single action

Speaker 2 in your trajectory.

Speaker 2 So that means that if you are doing

Speaker 2 something that goes for a long time, if you're training a task that takes a long time to solve, you will do no learning at all

Speaker 2 until you come up with a proposed solution. That's how reinforcement learning is done naively.
That's how O1, R1 ostensibly are done.

Speaker 2 The value function says something like, okay, look,

Speaker 2 maybe I could sometimes, not always,

Speaker 2 could tell you if you are doing well or badly.

Speaker 2 The notion of a value function is more useful in some domains than others. So for example, when you play chess

Speaker 2 and you lose a piece, you know, I messed up.

Speaker 2 You don't need to play the whole game to know that what I just did was bad, and therefore,

Speaker 2 whatever preceded it was also bad. So, the value function lets you short-circuit the wait until the very end.
Like, let's suppose that you started to pursue some kind of,

Speaker 2 okay, let's suppose that you are doing some kind of a math thing or a programming thing, and you're trying to explore a particular solution direction.

Speaker 2 And after, let's say, after a thousand

Speaker 2 steps of thinking, you concluded that this direction is unpromising.

Speaker 2 As soon as you conclude this, you could already get a reward signal a thousand time steps previously when you decided to pursue down this path.

Speaker 2 You say, oh, next time, I shouldn't pursue this path in a similar situation, long before you actually came up with the proposed solution.

Speaker 1 This was in the Deep Sea Gar 1 paper: is that the

Speaker 1 space of trajectories is so

Speaker 1 wide

Speaker 1 that maybe it's hard to learn a mapping from an intermediate trajectory and value.

Speaker 1 And also, given that, you know, in coding, for example, you'll have the wrong idea, then you'll go back, then you'll change something.

Speaker 2 This sounds like such lack of faith in deep learning.

Speaker 2 Like, I mean, sure, it might be difficult, but nothing deep learning can do. Yeah.

Speaker 2 So.

Speaker 2 My expectation is that

Speaker 2 like value functions should be useful and

Speaker 2 and I fully I fully expect that they will be used in the future if not already what was I alluding to with the person whose emotional center got

Speaker 2 damaged is more that

Speaker 2 maybe what it suggests is that the value function of humans is modulated by emotions in some important way that's hard-coded by evolution

Speaker 2 And maybe that is important for people to

Speaker 2 be effective in the world.

Speaker 1 That's the thing I was actually kind of planning on asking you.

Speaker 1 There's something really interesting about emotions of the value function, which is that it's impressive that they have this much utility while still being rather

Speaker 1 simple to understand.

Speaker 2 So I have two responses. I do agree that compared to...

Speaker 2 The kind of things that we learn and the things that we are talking about, the kind of ways we are talking about, emotions are relatively simple.

Speaker 2 They might even be so simple that maybe you could map them out in a human understandable way. I think it would be cool to do.

Speaker 2 In terms of utility, though, I think there is a thing where, you know, there is this complexity, robustness, trade-off,

Speaker 2 where complex things can be very useful,

Speaker 2 but simple things are very useful in a very broad range of situations.

Speaker 2 And so I think what one way to interpret what we are seeing is that we've got these emotions that essentially evolved mostly from our mammal ancestors and then fine-tuned a little bit while we were hominids, just a bit.

Speaker 2 We do have like a decent amount of social emotions though, which mammals may lack.

Speaker 2 But they're not very sophisticated. And because they're not sophisticated, they serve us so well in this very different world compared to the one that we've been living in.

Speaker 2 Actually, they also make mistakes. For example, our emotions, well, I don't know, does hunger count as an emotion?

Speaker 2 It's debatable, but I think, for example, our intuitive feeling of hunger

Speaker 2 is not succeeding in guiding us correctly in this world with an abundance of food.

Speaker 1 Yeah, people have been talking about scaling data,

Speaker 1 scaling parameters, scaling compute.

Speaker 1 Is there a more general way to think about scaling? What are the other scaling axes?

Speaker 2 So

Speaker 2 the thing, so

Speaker 2 here is a perspective. Here's a perspective I think might be might be true.

Speaker 1 So

Speaker 2 the way ML used to work is that people would just increase with stuff and try to

Speaker 2 get interesting results. That's what's been going on in the past.

Speaker 2 Then

Speaker 2 the scaling insight arrived, right? Scaling laws, GPT-3.

Speaker 2 And suddenly everyone realized we should scale.

Speaker 2 And it's just this, this is an example of how language affects thought.

Speaker 2 Scaling is just one word, but it's such a powerful word because it informs people what to do. They say, okay, let's try to scale things.
And so you say, okay, so what are we scaling?

Speaker 2 And pre-training was a thing to scale.

Speaker 2 It was a particular scaling recipe yes the big breakthrough of pre-training is the realization that this recipe is good so you say hey if you mix some compute with some data into a neural net of a certain size you will get results and you will know that you'll be better if you just scale the recipe up And this is also great.

Speaker 2 Companies love this because it gives you a very

Speaker 2 low-risk way of investing your resources.

Speaker 2 It's much harder to invest your resources in research. Compare that.

Speaker 2 If you research, you need to have like go forth researchers and research and come up with something versus get more data, get more compute, you know, you'll get something from pre-training.

Speaker 2 And indeed, you know, it looks like I, based on various

Speaker 2 things people say on to some people say on Twitter, maybe it appears the Gemini have found a way to get more out of pre-training. At some point, though, pre-training will run out of data.

Speaker 2 The data is very clearly finite. And so then, okay, what do you do next?

Speaker 2 Either you do some kind of souped up pre-training, different recipe from the one we've done before, or you're doing RL, or maybe something else.

Speaker 2 But now that compute is big, computer is now very big, in some sense, we are back to the age of research. So maybe here's another way to put it.
Up until 2020,

Speaker 2 from 2012 to 2020, it was the age of research. Now, from 2020 to 2025, it was the age of scaling.

Speaker 2 Or maybe plus, minus, let's add arrow bars to those years, because people say, this is amazing, you got to scale more, keep scaling, the one word, scaling. But now the scale is so big, like,

Speaker 2 is the belief really that, oh, it's so big, but if you had 100x more, everything would be so different? Like, it would be different for sure.

Speaker 2 But, like, is the belief that if you just 100x the scale, everything would be transformed? I don't think that's true. So it's back to the age of research again, just with big computers.

Speaker 1 That's a very interesting way to put it.

Speaker 1 But let me ask you the question you just posed then. What are we scaling and what would it mean to have a recipe? Because I guess I'm not aware of a very clean

Speaker 1 relationship that almost looks like a law of physics, which existed in pre-training. There was a power law between data or computer parameters and loss.

Speaker 1 What is the kind of relationship we should be seeking? And how should we think about what this new recipe might look like?

Speaker 1 So

Speaker 2 we've already witnessed a transition from

Speaker 2 one type of scaling to a different type of scaling, from pre-training to RL.

Speaker 2 Now people are scaling RL. Now based on what people say on Twitter, they spend more compute on RL than on pre-training at this point, because RHEL can actually consume quite a bit of compute.

Speaker 2 You know, you do very, very long rollouts. Yes.

Speaker 2 So it takes a lot of compute to produce those rollouts. And then you get a relatively small amount of learning per rollout.
So

Speaker 2 you really can spend a lot of compute.

Speaker 2 And I could imagine.

Speaker 2 Like I wouldn't at this stage it's more like I wouldn't even call it a scale um scaling. I would say, hey, like what are you doing? And is the thing you are doing

Speaker 2 the most productive thing you could be doing? Can you find a most more productive way of using your compute?

Speaker 2 We've discussed the value function business earlier and maybe once people get good at value functions, they will be using their resources more productively.

Speaker 2 And if you find a whole other way of training models, you could say, is this scaling or is it just using your resources? I think it becomes a little bit ambiguous.

Speaker 2 In a sense that when people were in the age of research, back then it was like people say, hey, let's try this and this and this. Let's try that and that.
Oh, look, something interesting is happening.

Speaker 2 And I think there will be a return to that.

Speaker 1 So if we were back in the era of research, stepping back, what is the part of the recipe that we need to think most about?

Speaker 1 When you say value function, people are already trying the current recipe, but then having LLM as a judge and so forth.

Speaker 1 You could say that's a value function, but it sounds like you have something much more fundamental in mind.

Speaker 1 Do we need to go back to,

Speaker 1 should we even rethink pre-training at all and not just add more steps to the end of that process? Yeah.

Speaker 2 So

Speaker 2 the discussion about value function, I think it was interesting. I want to emphasize that I think the value function is something like

Speaker 2 it's going to make our realm more efficient.

Speaker 2 And I think that makes a difference. But I think that anything you can do with the value function, you can do without just more slowly.

Speaker 2 The thing which I think is the most fundamental is that these models somehow just generalize dramatically worse than people. Yes.

Speaker 2 And it's super obvious.

Speaker 2 That seems like a very fundamental thing. Okay.

Speaker 1 So this is the crux generalization.

Speaker 2 And there's two

Speaker 1 sub-questions.

Speaker 1 There's one, which is about sample efficiency, which is why should it take so much more data for these models to learn than humans?

Speaker 1 There's a second about even separate from the amount of data it takes, takes, there's a question of why is it so hard to teach the thing we want to a model than to a human, which is to say

Speaker 1 for to a human, we don't necessarily need a verifiable reward to be able to,

Speaker 1 you're probably mentoring a bunch of researchers right now and you're talking with them, you're showing them your code and you're showing them how you think.

Speaker 1 And from that, they're picking up your way of thinking and how they should do research. You don't have to set like a verifiable reward for them.

Speaker 1 That's like, okay, this is the next part of the curriculum. And now this is the next part of your curriculum.

Speaker 1 And oh, it was this training was unstable, and we gotta, there's not this schleppy-bespoke process.

Speaker 1 So perhaps these two issues are actually related in some way. But I'd be curious to

Speaker 1 explore this second thing, which feels more like continual learning, and this first thing, which feels just like

Speaker 1 sample efficiency.

Speaker 2 Yeah. So, you know, you could actually wonder: one possible explanation for

Speaker 2 the human sample efficiency that needs to be considered is evolution.

Speaker 2 And evolution has given us a small amount of

Speaker 2 the most useful information possible.

Speaker 2 And for things like vision, hearing, and locomotion, I think there's a pretty strong case that evolution actually has given us a lot.

Speaker 2 So for example, human dexterity far exceeds, I mean

Speaker 2 Robots can become dexterous too if you subject them to like a huge amount of training and simulation.

Speaker 2 But to train a robot in the real world to quickly pick up a new skill like a person does seems very out of reach.

Speaker 2 And here you could say, oh, yeah, like locomotion, all our ancestors needed great locomotion. Squirrels, like

Speaker 2 so. Locomotion maybe like we've got like some unbelievable prior.
You could make the same case for vision. You know, I believe Yamli Khan made the point: oh, like

Speaker 2 children learn to drive after 16 hours after like 10 hours of practice, which is true. But our vision is so good.

Speaker 2 At least for me, when I remember myself being five-year-old,

Speaker 2 I was very excited about cars back then.

Speaker 2 And I'm pretty sure my car recognition was more than adequate for self-driving already as a five-year-old. You don't get to see that much data as a five-year-old.

Speaker 2 You spend most of your time in your parents' house. So you have very low data diversity.
But you could say maybe that's evolution too.

Speaker 2 But then language and math and coding, probably not.

Speaker 1 It still seems better than models. I mean, obviously, models are better than the average human at language and math and coding, but are they better at the average human at learning?

Speaker 2 Oh, yeah. Oh, yeah, absolutely.
What I meant to say is that language, math, and coding, and especially math encoding, suggests that whatever it is that makes people

Speaker 2 good at learning

Speaker 2 is probably not so much a complicated prior, but something more, some fundamental thing.

Speaker 1 Wait, I'm not sure I I understood. Why should that be the case?

Speaker 2 So, consider a skill

Speaker 2 that people exhibit some kind of great reliability, or, you know,

Speaker 2 if the skill is one that was very useful to our ancestors for many millions of years, hundreds of millions of years, you could say, you could argue that maybe humans are good at it

Speaker 2 because of evolution, because we have a prior, an evolutionary prior that's encoded in some very non-obvious way

Speaker 2 that somehow makes us so good at it.

Speaker 2 But if people exhibit great ability, reliability, robustness, ability to learn in a domain that really did not exist until recently,

Speaker 2 then this is more an indication that people might have

Speaker 2 just better machine learning period.

Speaker 1 But then how should we think about what that is? Is it a matter of,

Speaker 1 yeah, what is the ML analogy for why?

Speaker 1 There's a couple interesting things about it. It takes fewer samples.
It's more unsupervised. You don't have to set a very, like, a child learning to drive a car.

Speaker 1 Children are not learning to drive a car. A teenager learning how to drive a car is like not exactly getting

Speaker 1 some

Speaker 1 pre-built verifiable reward.

Speaker 1 It comes from their interaction with the machine and with the environment.

Speaker 1 And yet, it takes much of your samples, it seems more unsupervised, it seems more robust, much more robust.

Speaker 2 The robustness of people is really staggering.

Speaker 1 Yeah, so it's like, okay, and do you have a unified way of thinking about why are all these things happening at once? What is the ML analogy that would

Speaker 1 that could be, it could realize something like this?

Speaker 2 So, so, so, um, this is where, you know, one of the things that you've been asking about is how can, you know, know, the teenage driver kind of self-correct and learn from their experience without an external teacher?

Speaker 2 And the answer is, well, they have their value function, right? They have a general sense, which is also, by the way, extremely robust in people. Like

Speaker 2 whatever it is, the human value function, whatever the human value function is, with a few exceptions around addiction, it's actually very, very robust.

Speaker 2 And so for something like like a teenager that's learning to drive, they start to drive and they already have a sense of how they're driving immediately, how badly they are unconfident.

Speaker 2 And then they see, okay, and they, and then, of course, the learning speed of any teenager is so fast. After 10 hours, you're good to go.
Yeah.

Speaker 1 It seems like humans have some solution, but I'm curious about like, well, how are they doing it?

Speaker 1 And like, why is it so hard to like, how do we need to reconceptualize the way we're training models to make something like this possible?

Speaker 2 You know, that is a great question to ask.

Speaker 2 And it's a question

Speaker 2 I have a lot of opinions about.

Speaker 2 But unfortunately, we live in a world where not all machine learning ideas are discussed freely. And this is one of them.
So

Speaker 2 there's probably a way to do it.

Speaker 2 I think it can be done. The fact that people

Speaker 2 are like that, I think it's a proof that it can be done. There may be another blocker though, which is there is a possibility

Speaker 2 that the human neurons actually do more compute than we think.

Speaker 2 And if that is true, and if that plays an important role, then things might be more difficult. But regardless, I do think it points to the existence of some

Speaker 2 machine learning principle that I have opinions on. But unfortunately, circumstances make it hard to discuss in detail.

Speaker 1 Nobody listens to this podcast, Ilya.

Speaker 2 Yeah.

Speaker 1 So I have to say that prepping for Ilya was pretty tough because neither I nor anybody else had any idea what he's working on and what SSI is trying to do. I had no basis to come up with my questions.

Speaker 1 And the only thing I could go off, honestly, was trying to think from first principles about what are the bottlenecks to HEI? Because clearly Ilya is working on them in some way.

Speaker 1 Part of this question involved thinking about RL scaling because everybody's asking how well RL will generalize and how we can make it generalize better.

Speaker 1 As part of this, I was reading this paper that came out recently on RL scaling and it showed that actually the learning cover on RL looks like a sigmoid. I found this very curious.

Speaker 1 Why should it be a sigmoid? Where it learns very little for a long time and then it quickly learns a lot and then it asymptotes.

Speaker 1 This is very different from the power law you see in pre-training where the model learns a bunch at the very beginning and then less and less over time.

Speaker 1 And it actually reminded me of a note that I had written down after I had a conversation with a researcher friend where he pointed out that the number of samples that you need to take in order to find a correct answer scales exponentially with how different your current probability distribution is from the target probability distribution.

Speaker 1 And I was thinking about how these two ideas are related. I had this vague idea that they should be connected, but I really didn't know how.

Speaker 1 I don't have a math background, so I couldn't really formalize it. But I wondered if Gemini 3 could help me out here.

Speaker 1 And so I took a picture of my notebook and I took the paper and I put them both in the context of Gemini 3 and I asked it to find the connection. And it thought a bunch.

Speaker 1 And then it realized that the correct way to model the information you gain from a single yes or no outcome in RL is as the entropy of a random binary variable.

Speaker 1 It made a graph which showed how the bits you gain for a sample in RL versus supervised learning scale as the pass rate increases.

Speaker 1 And as soon as I saw the graph that Gemini 3 made, immediately a ton of things started making sense to me. Then I wanted to see if there was any empirical basis to this theory.

Speaker 1 So I asked Gemini to code on an experiment to show whether the improvement in loss scales in this way with pass rate.

Speaker 1 I just took the code that Gemini outputted, I copy-pasted it into a Google Colab notebook, and I was able to run this toy ML experiment and visualize its results without a single bug.

Speaker 1 It's interesting because the results look similar, but not identical to what we should have expected. And so I downloaded this chart and I put it into Gemini and I asked it, what is going on here?

Speaker 1 And it came up with a hypothesis that I think is actually correct, which is that we're capping how much supervised learning can improve in the beginning by having a fixed learning rate.

Speaker 1 And in fact, we should decrease the learning rate over time.

Speaker 1 It actually gives us an intuitive understanding for why in practice we have learning rate schedulers that decrease the learning rate over time.

Speaker 1 I did this entire flow from coming up with this vague initial question to building a theoretical understanding to running some toy ML experiments, all with Gemini 3.

Speaker 1 This feels like the first model where it can actually come up with new connections that I wouldn't have anticipated.

Speaker 1 It's actually now become the default place I go to when I want to brainstorm new ways to think about a problem.

Speaker 1 If you want to read more about RL scaling, you can check out the blog post that I wrote with a little help from Gemini 3. And if you want to check out Gemini 3 yourself, go to gemini.google.

Speaker 1 I am curious if you say we are back in the era of research.

Speaker 1 You were there from 2012 to 2020.

Speaker 1 And do you have,

Speaker 1 yeah, what is now the vibe going to be if we go back to the era of research? For example,

Speaker 1 even after AlexNet, the amount of compute that was used to run experiments kept increasing and the size of Frontier systems kept increasing.

Speaker 1 And

Speaker 1 do you think now that this era of research will still require tremendous amounts of compute?

Speaker 1 Do you think it will require going back into the archives and reading old papers? What is

Speaker 1 maybe what was the vibe of like you were at Google and

Speaker 1 OpenAI and Stanford and these places when there was like a more of a vibe of research.

Speaker 1 What kind of things should we be expecting in the community?

Speaker 2 So

Speaker 2 one consequence of the age of scaling is that there was this

Speaker 2 scaling sucked out all the air in the room. Yeah.

Speaker 2 And so

Speaker 2 Because scaling sucked out all the air in the room,

Speaker 2 everyone started to do the same thing.

Speaker 2 We got to the point where

Speaker 2 we are in a world where there are more companies than ideas by quite a bit actually on that you know there is the silicon valley saying that says that ideas are cheap execution is everything

Speaker 2 and people say that a lot yeah and there is truth to that but then i saw i saw someone say on twitter

Speaker 2 something like

Speaker 2 if ideas are so cheap how come no one's having any ideas

Speaker 2 And I think it's true too. I think,

Speaker 2 like, if you think about

Speaker 2 a research progress in terms of bottlenecks,

Speaker 2 there are several bottlenecks. If you go back to the, if you, and one of them is ideas, and one of them is your ability to bring them to life, which might be compute, but also engineering.

Speaker 2 So, if you go back to the 90s, let's say, you had people who had pretty good ideas. And if they had much larger computers, maybe they could demonstrate that their ideas were viable.

Speaker 2 But they could not.

Speaker 2 So they could only have very, very small demonstration and did not convince anyone.

Speaker 2 So the bottleneck was compute.

Speaker 2 Then in the age of scaling, computers increased a lot.

Speaker 2 And of course, there is a question of how much compute is needed, but compute is large.

Speaker 2 So

Speaker 2 compute is large enough such that

Speaker 2 it's like not obvious that you need that much more compute to prove some idea.

Speaker 2 Like, I'll give you an analogy. AlexNet was built on two GPUs.
That was the total amount of compute used for it. The Transformer

Speaker 2 was built on eight to 64 GPUs. No single Transformer paper experiment used more than 64 GPUs of 2017, which would be like, what, two GPUs of today?

Speaker 2 So the ResNet,

Speaker 2 right?

Speaker 2 Many, like, even the,

Speaker 2 you could argue that the like O1

Speaker 2 reasoning was not the most compute-heavy thing in the world. So there definitely

Speaker 2 for research,

Speaker 2 you need like definitely some amount of compute, but it's far from obvious that you need the absolutely largest amount of compute ever for research.

Speaker 2 You might argue, and I think it is true, that if you want to build the absolutely best system,

Speaker 2 if you want to build the absolutely best system then it helps to have much more compute and especially if everyone is within the same paradigm then compute becomes one of the big differentiators

Speaker 1 yeah i guess while it was possible to develop these ideas i'm asking you for the history because you were actually there i'm not sure what actually happened but it sounds like it was possible to develop these ideas using minimal amounts of compute but it wasn't the transformer didn't immediately become famous it became the thing everybody started doing and then started experimenting on top of and building on top of because it was validated at higher and higher levels of compute.

Speaker 2 Correct.

Speaker 1 And if you at SSI have 50 different ideas, how will you know which one is the next transformer and which one is

Speaker 1 brittle

Speaker 1 without having the kinds of compute that other frontier labs have?

Speaker 2 So I can comment on that, which is

Speaker 2 the short comment is that

Speaker 2 you mentioned SSI. Specifically, for us,

Speaker 2 the amount of compute that SSI has for research is really

Speaker 2 not that small. And I want to explain why, like a simple math can explain why the amount of compute that we have is actually a lot more comparable for research than one might think.

Speaker 2 Now, explain.

Speaker 2 So,

Speaker 2 SSI has raised $3 billion,

Speaker 2 which is like

Speaker 2 not small, but it's like a lot by any absolute sense. But you could say, but look at the other companies raising much more.

Speaker 2 But

Speaker 2 a lot of their compute goes for inference.

Speaker 2 Like these big numbers, these big loans get earmarked for inference. That's number one.

Speaker 2 Number two, you need if you want to have a product on which you do inference, you need to have a big staff of engineers, of salespeople.

Speaker 2 A lot of the research needs to be be dedicated for producing all kinds of product-related features. So then when you look at what's actually left for research, the difference becomes a lot smaller.

Speaker 2 Now, the other thing is, is that if you are doing something different,

Speaker 2 do you really need the absolute maximal scale to prove it? I don't think that's true at all. I think that in our case, we have

Speaker 2 sufficient compute to prove to convince ourselves and anyone else that what we're doing is correct.

Speaker 1 There's been public estimates that companies like OpenAI spend on the order of five, six billion dollars a year,

Speaker 1 just so far on experiments.

Speaker 1 This is separate from the amount of money they're spending on inference and so forth.

Speaker 1 So it seems like they're spending more a year running experi like research experiments than you guys have in total funding.

Speaker 2 I think it's a question of what you do with it. It's a question of what you do with it.

Speaker 2 Like they have a like is the more I think in in their case, in the case of others, I think there is a lot more demand on the training compute. There's a lot more different work streams.

Speaker 2 There are different modalities. There is just more stuff.
And so it becomes fragmented.

Speaker 1 How will SSI make money?

Speaker 2 You know,

Speaker 2 my answer to this question is something like...

Speaker 2 We just focus right now, we just focus on the research, and then the answer to that question will reveal itself. I think there will be lots of possible answers.

Speaker 1 Is SSI's plan still to straight shot super intelligence?

Speaker 2 Maybe.

Speaker 2 I think that there is merit to it. I think there's a lot of merit because I think that it's very nice to not be affected by the day-to-day market competition.

Speaker 2 But

Speaker 2 I think there are two reasons that may cause us to change the plan. One is pragmatic if timelines turned out to be long,

Speaker 2 which they might.

Speaker 2 And second, I think there is a lot of value in

Speaker 2 the best and most powerful AI being out there impacting the world.

Speaker 2 I think this is a meaningfully valuable thing.

Speaker 1 But then, so why is your default plan to straight-shot superintelligence?

Speaker 1 Because it sounds like, you know, OpenAI, Anthropic, all these other companies, their explicit thinking is, look, we have weaker and weaker intelligences that the public can get used to and prepare for.

Speaker 1 And why is it potentially better to build a super intelligence directly?

Speaker 2 So I'll make the case for and against.

Speaker 2 The case four is that you are, so one of the challenges that people face when they're in the market is that they have to participate in the rat race.

Speaker 2 And the rat race is quite difficult in that it exposes you to

Speaker 2 difficult trade-offs which you need to make.

Speaker 2 And there is, it is, it is nice nice to say we'll insulate ourselves from all this and just focus on the research and come out only when we are ready and not before.

Speaker 2 But the counterpoint is valid too.

Speaker 2 And

Speaker 2 those are opposing forces. The counterpoint is, hey, it is useful for the world to see powerful AI.

Speaker 2 It is useful for the world to see powerful AI because that's the only way you can communicate it.

Speaker 1 Well, I guess not even just that you can communicate the idea, but...

Speaker 2 Communicate the AI, not the idea, communicate the AI.

Speaker 1 What do you mean, communicate the AI?

Speaker 2 Okay, so let's suppose you read an essay about AI. And the essay says AI is going to be this, and AI is going to be that, and it's going to be this.

Speaker 2 And you read it, and you say, okay, this is an interesting essay.

Speaker 2 Now, suppose you see an AI doing this, an AI doing that.

Speaker 2 It is incomparable. Like, basically,

Speaker 2 I think that there is a big benefit from AI being in the public. And

Speaker 2 that would be a reason for us to not be quite straight shot. Yeah.

Speaker 1 Well, I guess it's not even that, but I do think that is an important part of it. The other big thing is, I can't think of another discipline in human engineering and research where

Speaker 1 the end artifact was made safer

Speaker 1 mostly through just thinking about how to make it safe, as opposed to why are airplane crashes per mile so much lower today than they were decades ago?

Speaker 1 Why is is it so much harder to find a bug in Linux than it would have been decades ago? And I think it's mostly because these systems were deployed to the world. You noticed failures.

Speaker 1 Those failures were corrected and the systems became more robust. And I'm not sure why AGI and superhuman intelligence would be any different, especially given, and I hope

Speaker 1 we're going to get to this.

Speaker 1 It seems like the harms of super intelligence are not just about like having some malevolent paper clipper out there, but it's just like this is a really powerful thing, and we don't even know how to conceptualize how people will interact with it, what people will do with it.

Speaker 1 And having gradual access to it seems like a

Speaker 1 better way to maybe spread out the impact of it and to help people prepare for it.

Speaker 2 Well, I think on this point, even in the straight shot scenario, you would still do a gradual release of it.

Speaker 2 It's how I would imagine it.

Speaker 2 The

Speaker 2 gradualism would be an

Speaker 2 inherent component of any plan. It's just a question of what is the first thing that you get out of the door.
That's number one.

Speaker 2 Number two, I also think, you know, I believe you have advocated for continual learning more than other people. And I actually think that this is an important and correct thing.
And here is why.

Speaker 2 So, one of the things, so I'll give you another example of how thinking, how language affects thinking.

Speaker 2 And in this case, it will be two words, two words that have shaped everyone's thinking, I maintain.

Speaker 2 First word, AGI.

Speaker 2 Second word, pre-training. Let me explain.

Speaker 2 So

Speaker 2 the term AGI,

Speaker 2 why does this term exist? It's a very particular term. Why does it exist? There's a reason.

Speaker 2 The reason that the term AGI exists is, in my opinion, not so much because it's like a very important essential descriptor of

Speaker 2 some end state of intelligence but

Speaker 2 because it is a reaction to a different term that existed and the term is narrow AI if you go back to ancient history of gameplay and AI of checkers AI chess AI computer games AI everyone would say look at this narrow intelligence sure the chess ai can beat Kasparov but it can't do anything else it is so narrow artificial narrow intelligence so in response as a reaction to this some people said well this is not good it is so narrow what we need is general ai

Speaker 2 general ai an ai that can just do all the things

Speaker 2 the second

Speaker 2 and and that term just got a lot of traction.

Speaker 2 The second thing that got a lot of traction is pre-training. Specifically, the recipe of pre-training.
I think the current, the way people do RL now is maybe

Speaker 2 undoing the conceptual imprint of pre-training. But pre-training had the property: you do more pre-training, and the model gets better at everything more or less uniformly.

Speaker 2 General AI. Pre-training gives AGI.

Speaker 2 But

Speaker 2 the thing that happened with AGI and pre-training is that in some sense they overshot the target.

Speaker 2 Because by the kind, if you think about the term AGI, you will realize, and especially in the context of pre-training, you will realize that a human being is not an AGI.

Speaker 2 Because a human being, yes, there is definitely a foundation of skills.

Speaker 2 A human being lacks a huge amount of knowledge. Instead, we rely on continual learning.

Speaker 2 We rely on continual learning. And so then, when you think about, okay, so let's suppose that we achieve success and we produce

Speaker 2 some kind of safe super intelligence. The question is, but how do you define it? Where on the curve of continual learning is it going to be?

Speaker 2 I produce like a super intelligent 15-year-old that's very eager to go, and you say, okay, I'm going to, they don't know very much at all. The great student, very eager.
You go and be a programmer.

Speaker 2 You go and be a doctor.

Speaker 2 Go and learn. So you could imagine that the deployment itself will involve some kind of a learning trial and error period.
It's a process, as opposed to you drop the finished thing.

Speaker 1 Okay, I see. So you're suggesting that the thing you're pointing out with super intelligence is not some finished

Speaker 1 mind which knows how to do every single job in the economy. Because the way, say,

Speaker 1 the original, I think, OpenAI Charter or whatever defines AGI is like, it can do every single job that every single thing a human can do.

Speaker 1 You're proposing instead a mind which can learn to do any single, every single job. Yes.
And that is super intelligence. And then, but once you have the learning algorithm,

Speaker 1 it gets deployed into the world the same way a human laborer might join an organization. And it seems like one of these two things might happen.
Maybe neither of these happens. One,

Speaker 1 this

Speaker 1 super efficient learning algorithm becomes superhuman, becomes as good as you and potentially even better at the task of ML research.

Speaker 1 And as a result, the algorithm itself becomes more and more superhuman. The other is, even if that doesn't happen, if you have a single model, I mean, this is explicitly your vision.

Speaker 1 If you have a single model, or instances of a model, which are deployed through the economy, doing different jobs, learning how to do those jobs, continually learning on the job, picking up all the skills that any human could pick up, but actually picking them all up at the same time and then amalgamating the learnings.

Speaker 1 You basically have a model which functionally becomes super intelligent even without any sort of recursive self-improvement in software, right?

Speaker 1 Because you now have one model that can do every single job in the economy, and humans can't merge our minds in the same way.

Speaker 1 And so do you expect some sort of like intelligence explosion from broad deployment?

Speaker 2 I think

Speaker 2 that it is likely that we will have rapid economic growth.

Speaker 2 I think the broad deployment,

Speaker 2 like

Speaker 2 there are two arguments you could make, which are conflicting.

Speaker 2 One is that, look, if indeed you get, once indeed

Speaker 2 you get to a point where you have an AI that can learn to do

Speaker 2 things quickly,

Speaker 2 and you have many many of them, then

Speaker 2 they will be a strong force to deploy them in the economy, unless there will be some kind of a regulation that stops it, which by the way, there might be.

Speaker 2 But

Speaker 2 I think the idea of very rapid economic growth for some time, I think it's very possible from broad deployment. Then the question is, how rapid is it going to be?

Speaker 2 So I think this is hard to know, because on the one hand, you have this very efficient worker. On the other hand, the world is just really big and there's a lot of stuff.

Speaker 2 And that stuff moves at a different speed. But then on the other hand, now the AI could,

Speaker 2 you know, so I think very rapid economic growth is possible.

Speaker 2 And we will see like all kinds of things, like different countries with different rules and the ones which have the friendlier rules, the economic growth will be faster. Hard to predict.

Speaker 1 Some people in our audience like to read the transcripts instead of listening to the episode. And so we put a ton of effort into making the transcripts read like they are standalone essays.

Speaker 1 The problem is that if you just transcribe a conversation verbatim using a speech-to-text model, it'll be full of all kinds of fits and starts and confusing phrasing.

Speaker 1 We mentioned this problem to LabelBox and they asked if they could take a stab. Working with them on this is probably the reason that I'm most excited to recommend Labelbox to people.

Speaker 1 It wasn't just, oh, hey, tell us what kind of data you need and we'll go get it.

Speaker 1 They walked us through the entire process, from helping us identify what kind of data we needed in the first place to assembling a team of expert aligners to generate it.

Speaker 1 Even after we got all the data back, LabelBox stayed involved. They helped us choose the right base model and set up auto QA on the model's output so that we could tweak and refine it.

Speaker 1 And now we have a new transcriber tool that we can use for all our episodes moving forward.

Speaker 1 This is just one example of how LabelBox meets their customers at the ideas level and partners with them through their entire journey.

Speaker 1 If you want to learn more, or if you want to try out the transcriber tool yourself, go to labelbox.com slash dwar cache.

Speaker 1 It seems to me that this is a very precarious situation to be in where,

Speaker 1 looking the limit, we know that this should be possible because if you have something that is as good as a human at learning, but which can merge its brains, merge their different instances in a way that humans can't merge.

Speaker 1 Already this seems like a thing that should physically be possible. Humans are possible.
Digital computers are possible. You just need both of those combined to produce this thing.

Speaker 1 And it also seems like this kind of thing is extremely

Speaker 1 powerful.

Speaker 1 And

Speaker 1 economic growth is one way to put it. I mean, Dyson Spear is a lot of economic growth.

Speaker 1 But another way to put it is just like, you will have potentially a very short period of time because a human on the job can, you know, you're hiring people at SSI in six months, they're like net productive probably, right?

Speaker 1 A human like learns really fast. And so this thing is becoming smarter and smarter very fast.
What is how do you think about making that go well? And why is SSI positioned to do that well?

Speaker 1 Or does SSI's plan there, basically, is what I'm trying to ask?

Speaker 2 Yeah,

Speaker 2 so

Speaker 2 one of the ways in which my thinking has been changing is that

Speaker 2 I now place more importance on AI

Speaker 2 being

Speaker 2 deployed incrementally and in advance. One very difficult thing about AI is that we are talking about

Speaker 2 systems that don't yet exist.

Speaker 2 And it's hard to imagine them.

Speaker 2 I think that one of the things that's happening is that in practice, it's very hard to feel the AGI.

Speaker 2 It's very hard to feel the AGI.

Speaker 2 We can talk about it,

Speaker 2 but it's like it's like talking about like the long future. Like, imagine having a conversation about how it is like to be old when you're old and frail.

Speaker 2 And you can have a conversation, you can try to imagine it, but

Speaker 2 it's just hard, and you come back to reality where that's not the case. And I think that a lot of the

Speaker 2 issues around

Speaker 2 AGI and its future power stem from the fact that it's very difficult to imagine.

Speaker 2 Future AI is going to be different. It's going to be powerful.
Indeed, the whole problem, what is the problem of AI and AGI?

Speaker 2 The whole problem is the power.

Speaker 2 The whole problem is the power.

Speaker 2 When the power is really big, what's going to happen?

Speaker 2 And

Speaker 2 one of the ways in which I've changed my mind over the past year, and so

Speaker 2 that

Speaker 2 change of mind may back

Speaker 2 may, I'll say, I'll hedge a little bit, may backpropagate into the plans of our company, is that

Speaker 2 so if it's hard to imagine,

Speaker 2 what do you do? You got to be showing the thing. You got to be showing the thing.
And I maintain that,

Speaker 2 I think most people who work on AI also can't imagine it because it's too different from what people see on a day-to-day basis.

Speaker 2 I do maintain, here's something which I predict will happen. That's a prediction.

Speaker 2 I maintain that as AI becomes more powerful, then people will change their behaviors.

Speaker 2 And we will see all kinds of unprecedented things which are not happening right now. And I'll give some examples.

Speaker 2 I think for better or worse,

Speaker 2 the frontier companies will play a very important role in what happens, as will the government. And the kind of things that I think you'll see, which you see the beginnings of,

Speaker 2 companies that are fierce competitors starting

Speaker 2 to collaborate on AI safety. You may have seen OpenAI and Anthropic

Speaker 2 doing a first small step. but that did not exist.
That's actually something which I predicted in one of my talks about three years ago, that such a thing will happen.

Speaker 2 I also maintain that as AI continues to become more powerful, more visibly powerful, there will also be a desire from governments and the public to do something.

Speaker 2 And I think that this is a very important force

Speaker 2 of showing the AI. That's number one.
Number two, okay, so then the AI is being built.

Speaker 2 What needs to be done?

Speaker 2 So one thing that I maintain that will happen is that right now, people who are working on AI

Speaker 2 are maintaining that the AI doesn't feel powerful because of its mistakes.

Speaker 2 I do think that at some point the AI will start to feel powerful, actually.

Speaker 2 And I think when that happens, we will see a big change in the way

Speaker 2 all AI companies approach safety. They'll become much more paranoid.

Speaker 2 I think I say this as a predict as

Speaker 2 a prediction that we will see happen. We'll see if I'm right.
But I think this is something that will happen because they will see the AI becoming more powerful.

Speaker 2 Everything that's happening right now, I maintain, is because people look at today's AI and it's hard to imagine the future AI.

Speaker 2 And there is a third thing which needs to happen. And I think this is this, this, and I'm talking about it in broader terms, not just from the perspective of SSI,

Speaker 2 because you asked me about our company. But the question is, okay, so then what should the companies aspire to build? What should they aspire to build?

Speaker 2 And there has been one big idea that actually every that everyone has been

Speaker 2 locked into, which is the self-improving AI.

Speaker 2 And why did it happen? Because there is fewer ideas than companies. But I maintain that there is something that's better to build.
And I think that everyone will actually want that. It's like

Speaker 2 the AI that's robustly aligned to care about sentient life specifically.

Speaker 2 I think in particular, it will be, there's a case to be made that it will be easier to build an AI that cares about sentient life than an AI that cares about human life alone, because the AI itself will be sentient.

Speaker 2 And if you think about things like mirror neurons and human empathy for animals, which is, you know, you might argue it's not big enough, but it exists.

Speaker 2 I think it's an emergent property from the fact that we model others with the same circuit that we use to model ourselves because that's the most efficient thing to do.

Speaker 1 So,

Speaker 1 even if you got an AI to hear about sentient beings,

Speaker 1 and it's not actually clear to me that that's what you should try to do if you solved alignment,

Speaker 1 it would still be the case that most sentient beings will be AIs. There will be trillions, eventually quadrillions of AIs.
Humans will be a very small fraction of sentient beings.

Speaker 1 So,

Speaker 1 it's not clear to me if the goal is some kind of human control over

Speaker 1 this future civilization, that this is the best criterion?

Speaker 2 It's true.

Speaker 2 I think that it's possible it's not the best criterion. I'll say two things.

Speaker 2 I think that

Speaker 2 thing number one,

Speaker 2 I think that if there so

Speaker 2 I think that care for sentient life, I think there is merit to it. I think it should be considered.
I think that it will be helpful if there was some kind of a

Speaker 2 shortlist of ideas that then

Speaker 2 the companies, when they are in this situation, could use. That's number two.

Speaker 2 Number three, I think it would be really materially helpful if the power of the most powerful super intelligence was somehow capped

Speaker 2 because it would address a lot of these concerns.

Speaker 2 The question of how to do it, I'm not sure, but I think that would be materially helpful when you're talking about really, really powerful systems.

Speaker 1 Before we continue the alignment discussion, I want to double-click on that. How much room is there at the top? How do you think about super intelligence? Do you think,

Speaker 1 I mean, using this learning efficiency idea, maybe it's just extremely fast at learning new skills or new knowledge? And does it just have a bigger pool of strategies? Is there a single cohesive it

Speaker 1 in the center that's more powerful or bigger? And if so,

Speaker 1 do you imagine that this will be sort of godlike in comparison to the rest of human civilization? Or does it just feel like another agent or another cluster of agents?

Speaker 2 So, this is an area where different people have different intuitions.

Speaker 2 I think it will be very powerful for sure. I think that what I think is most likely to happen

Speaker 2 is that there will be multiple such AIs

Speaker 2 being created roughly at the same time.

Speaker 2 I think that

Speaker 2 if the cluster is big enough,

Speaker 2 like if the cluster is literally continent-sized, that thing could be really powerful indeed.

Speaker 2 If you literally have a continent-sized cluster, like those, those AIs can be very powerful. And

Speaker 2 all I can tell you is that if you're talking about extremely powerful AIs, like truly dramatically powerful, then yeah, it would be nice if they could be restrained in some ways, or if there was some kind of an agreement or something

Speaker 2 because I think that if you are saying hey like if you really

Speaker 2 like what what is the the concern of superintelligence what is one way to explain the concern if you imagine a system that is sufficiently powerful like really sufficiently powerful

Speaker 2 and you could say okay you need to do something sensible like care for sentient life let's say in a very single-minded way we might not like the results that's really what it is And so maybe, by the way, the answer is that

Speaker 2 you do not build an RL agent in the usual sense. And actually,

Speaker 2 I'll point several things out. I think human beings are a semi-RL agent.
You know, we pursue a reward and then the emotions or whatever make us tire out of the reward. We pursue a different reward.

Speaker 2 The market is like... kind it's like a very short-sighted kind of agent.
Evolution is the same. Evolution is very intelligent in some ways, but very dumb in other ways.

Speaker 2 The government has been designed to be a never-ending fight between three parts, which has an effect. So, I think things like this.

Speaker 2 Another thing that makes this discussion difficult is that we are talking about systems that don't exist, that we don't know how to build.

Speaker 2 That's the other thing. And that's actually my belief.
I think what people are doing right now will go some distance and then peter out. It will continue to improve, but it will also not be it.

Speaker 2 So, the it,

Speaker 2 we don't know how to build. And I think that

Speaker 2 a lot hinges on

Speaker 2 understanding reliable generalization.

Speaker 2 Now say another thing, which is like,

Speaker 2 you know, one of the things that you could say is what cause alignment to be difficult is that human value that it's it's um

Speaker 2 your ability to learn human values is fragile, then your ability to optimize them is fragile, you will you actually learn to optimize them.

Speaker 2 And then can't you say, are these not all instances of unreliable generalization?

Speaker 2 Why is it that human beings appear to generalize so much better? What if generalization was much better? What would happen in this case? What would be the effect?

Speaker 2 But those we can't, we can't, like those questions are right now still unanswerable.

Speaker 1 How does one think about

Speaker 1 what AI going well looks like? Because I think you've scoped out how AI might evolve. We'll have these sort of continual learning agents.
AI will be very powerful.

Speaker 1 Maybe there will be many different AIs. How do you think about lots of continent compute size intelligences going around?

Speaker 1 How dangerous is that? How do we make that less dangerous? And how do we do that in a way that

Speaker 1 protects an equilibrium where there might be misaligned AIs out there and bad actors out there?

Speaker 2 So, one reason why I liked the AI that cares for sentient life, you know, and we can debate on whether it's good or bad, but

Speaker 2 if the first

Speaker 2 n of these dramatic systems actually do care for, you know,

Speaker 2 love humanity or something, you know, care for sentient life, obviously this also needs to be achieved. This needs to be achieved.

Speaker 2 So if this is achieved by the first n of those systems,

Speaker 2 then I can see it go well,

Speaker 2 at least for quite some time. And then there is the question of what happens in the long run.
What happens in the long run? How do you achieve a long-run equilibrium?

Speaker 2 And I think that

Speaker 2 there there is an answer as well. And I don't like this answer,

Speaker 2 but it needs to be considered.

Speaker 2 In the long run, you might say, okay, so if you have a world where powerful AIs exist,

Speaker 2 in the short run, you could say, okay, you have universal high income.

Speaker 2 You have universal high income.

Speaker 2 And we're all doing well. But we know that

Speaker 2 what do the Buddhists say? Change is the only constant. And so things change.
And there is some kind of government political structure thing. And it changes.
Because these things have a shelf life.

Speaker 2 You know, some new government thing comes up and it functions. And then after some time, it stops functioning.

Speaker 2 That's something that we see happening all the time. And so I think that for the long-run equilibrium,

Speaker 2 one approach, you could say, okay, so maybe every person will have an AI that will do their bidding. And that's good.
And if that could be maintained indefinitely, that's true.

Speaker 2 But the downside with that is, okay, so then the AI goes and like

Speaker 2 earns earn earn, you know, earns money for the person and advocates for their needs in like the political sphere, and maybe then writes a little report saying, okay, here's what I've done, here's the situation, and the person says, great, keep it up.

Speaker 2 But the person is no longer a participant.

Speaker 2 And then you can say that's a precarious place to be in.

Speaker 2 But, so I'm going to preface by saying,

Speaker 2 I don't like this solution, but it is a solution.

Speaker 2 And the solution is if people become part AI with some kind of Neuralink plus plus. Because what will happen as a result is that now the AI understands something and we understand it too.

Speaker 2 Because now the understanding is transmitted wholesale. So now, if the AI is in some situation, now it's like you are involved in that situation yourself fully.

Speaker 2 And I think this is the answer to the equilibrium.

Speaker 1 I wonder if

Speaker 1 the fact that emotions, which were

Speaker 1 developed millions, or in many cases, billions of years ago, in a totally different environment, are still guiding our actions so strongly is an example of alignment success.

Speaker 1 To maybe spell out what I mean,

Speaker 1 the brainstem has these,

Speaker 1 I don't know if it's more accurate to call it a value function or reward function, but the brainstem has a directive where it's saying, mate with somebody who's more successful.

Speaker 1 The cortex is the part that understands what does success mean in the modern context. But the brainstem is able to align.

Speaker 1 the cortex and say, however you recognize success to be, and I'm not smart enough to understand what that is, you're still going to pursue this directive.

Speaker 2 I think there is

Speaker 2 so I think there's a more general point. I think it's actually really mysterious how

Speaker 2 the brain encodes high-level desires. Sorry, how evolution encodes high-level desires.
Like, it's pretty easy to understand how evolution would endow us with the desire for food that smells good.

Speaker 2 Because smell is a chemical.

Speaker 2 And so just pursue that chemical. It's very easy to imagine such a mechanism, evolution doing such a thing.

Speaker 2 But

Speaker 2 evolution also has endowed us with all these social desires. Like we really care about being seen positively by society, we care about being in a good standing.

Speaker 2 Like all these social intuitions that we have, I feel strongly that they are baked in.

Speaker 2 And I don't know how evolution did it because it's a high-level concept. It's represented in the brain.
Like what people think, like let's say you are like, you care about

Speaker 2 some social thing.

Speaker 2 It's not like a low-level signal like smell. It's not something that for which there is a sensor.

Speaker 2 Like the brain needs to do a lot of processing to piece together lots of bits of information to understand what's going on socially. And somehow evolution said that's what you should care about.
Yes.

Speaker 2 How did it do it? And it did it quickly too. Yeah.
Because I think all these sophisticated social things that we care about, I think they evolved pretty recently.

Speaker 2 So evolution had an easy time hardcoding this high-level desire. And

Speaker 2 I maintain, or at least I'll say, I'm unaware of good hypothesis for how it's done. I had some ideas I was kicking around, but

Speaker 2 none of them

Speaker 2 are satisfying.

Speaker 1 Yeah.

Speaker 1 And what's especially impressive is if it was a desire that you learned in your lifetime, it kind of makes sense because your brain is intelligent, it makes sense why we're able to learn intelligent desires.

Speaker 1 But your point is that the desire is maybe this is not your point, but one way to understand it is the desire is built into the genome, and the genome is not intelligent, right?

Speaker 1 But it's able to, you're somehow able to describe this feature that requires, like, it's not even clear how you define that feature, and you can get it into the, you can build it into the genes.

Speaker 2 Yeah, essentially. Or maybe I'll put it differently.
If you think about the tools that are available to the genome,

Speaker 2 it says, okay, here's a recipe for building a brain. And you could say, here is a recipe for connecting the dopamine neurons to like the smell sensor.

Speaker 2 And if the smell is a certain kind of, you know, good smell, you want to eat that. I could imagine the genome doing that.

Speaker 2 I'm claiming that it is harder to imagine, it's harder to imagine the genome saying you should care about

Speaker 2 some complicated computation that your entire brain, that like a big chunk of your brain does. That's all I'm claiming.
I can tell you like a speculation. I was wondering how it could be done.

Speaker 2 And let me offer a speculation and I'll explain why the speculation is probably false. So the speculation is,

Speaker 2 okay,

Speaker 2 so the brain, it's like

Speaker 2 the brain has those regions, you know, the brain regions. We have our cortex, right? Yep.
It has all those brain regions. And the cortex is uniform, but the brain regions,

Speaker 2 and the neurons in the cortex, they kind of speak to their neighbors mostly. And that explains why you get get brain regions.

Speaker 2 Because if you want to do some kind of speech processing, all the neurons that do speech need to talk to each other.

Speaker 2 And because neurons can only speak to their nearby neighbors for the most part, it has to be a region. All the regions are mostly located in the same place from person to person.

Speaker 2 So maybe evolution hard-coded literally a location on the brain.

Speaker 2 So it says, oh, like when like, you know,

Speaker 2 the GPS of the brain, GPS coordinates, such and such, when that fires, that's what you should care about. Like maybe that's what evolution did, because that would be within the toolkit of evolution.

Speaker 1 Yeah, although there are examples where, for example, people who are born blind have that area of their cortex adopted by

Speaker 1 another sense.

Speaker 1 And I have no idea, but I'd be surprised if the

Speaker 1 desires or the reward functions which require visual signal no longer worked. You know, people who have their different areas of their cortex co-opted.
For example, if you no longer have vision,

Speaker 1 can you still feel the sense that I want people around me to like me and so forth, which usually there's also visual cues for?

Speaker 2 So, I actually fully agree with that. I think there's an even stronger counter-argument to this theory, which is like if you think about people, so there are people

Speaker 2 who get half of their brains removed in childhood.

Speaker 2 And they still have all their brain regions, but they all somehow move to just one hemisphere, which suggests that the brain regions,

Speaker 2 the location is not fixed. And so that theory is not true.
It would have been cool if it was true, but it's not. And so I think that's a mystery, but it's an interesting mystery.

Speaker 2 Like the fact is, somehow,

Speaker 2 evolution was able to endow us to care about social stuff very, very reliably.

Speaker 2 And even people who have like all kinds of strange mental conditions and deficiencies and emotional problems tend to care about this also.

Speaker 1 AI tools like D-Fakes, Voice Clones, and Agents have dramatically increased the sophistication of fraud and abuse.

Speaker 1 So it's more important than ever to actually understand the identity and intent of whoever or whatever is using your platform. That's exactly what Sardine helps you do.

Speaker 1 Sardine brings together thousands of device, behavior, and identity signals to help you assess risk.

Speaker 1 Everything from how a user types or moves their mouse or holds their device, to whether they're hiding their true location behind a VPN, to whether they're injecting a fake camera feed during KYC selfie checks.

Speaker 1 Sardine combines these signals with insights from their network of almost 4 billion devices. Things like a user's history of fraud or their associations with other high-risk accounts.

Speaker 1 So you can spot bad actors before they do damage. This would literally be impossible if you only use data from your own application.
Sardine doesn't stop at detection.

Speaker 1 They offer a suite of agents to streamline onboarding checks and automate investigations. So as fraudsters use AI to scale their attacks, you can use AI to scale your defenses.

Speaker 1 Go to sardine.ai slash swarakesh to learn more and download their guide on AI fraud detection.

Speaker 1 What is SSI planning on doing differently? So presumably your plan is to be one of the frontier companies when this time arrives.

Speaker 1 And then what is

Speaker 1 presumably you started SSI because you're like, I think I have a way of approaching how to do this safely in a way that the other companies don't.

Speaker 1 What is that difference?

Speaker 2 So, the way I would describe it is:

Speaker 2 there are some ideas that I think are promising, and I want to investigate them and see if they are indeed promising or not. It's really that simple.
It's an attempt.

Speaker 2 I think that if the ideas turn out to be correct, these ideas that we discussed around

Speaker 2 understanding generalization,

Speaker 2 if these ideas turn out to be correct,

Speaker 2 then I think we will have something worthy. Will they turn out to be correct? We are doing research.
We are squarely the age of research company. We are making progress.

Speaker 2 We've actually made quite good progress over the past year, but we need to keep making more progress, more research. And that's how I see it.
I see it as an attempt

Speaker 2 to be

Speaker 2 an attempt to be a voice and a participant.

Speaker 1 People have asked,

Speaker 1 your co-founder and previous CEO left to go to Meta recently.

Speaker 1 And people have asked, well, if there was a lot of breakthroughs being made, that seems like a thing that should have been unlikely. I wonder how you respond.

Speaker 2 Yeah, so

Speaker 2 for this, I will simply remind a few facts that may have been forgotten. And I think these facts, which provide the context, I think they explain the situation.

Speaker 2 So the context was that we were fundraising at a 32 billion valuation,

Speaker 2 and then Meta

Speaker 2 came in and offered to acquire us, and I said no.

Speaker 2 But my former co-founder,

Speaker 2 like in some sense, said yes.

Speaker 2 And as a result, he also was able to enjoy from a lot of near-term liquidity. And he was the only person from SSI to join Meta.

Speaker 1 It sounds like SSI's plan is to be a company that is at the frontier when you get to this

Speaker 1 very important period in human history where you have superhuman intelligence and you have these ideas about how to make superhuman intelligence go well,

Speaker 1 but other companies will be trying their own ideas. What distinguishes SSI's approach to making super intelligence go well?

Speaker 2 The main thing that distinguishes SSI

Speaker 2 is its technical approach. So we have a different technical approach that I think is worthy,

Speaker 2 and we are pursuing it.

Speaker 2 I maintain that in the end, there will be a convergence of strategies. So, I think there will be a convergence of strategies where

Speaker 2 at some point,

Speaker 2 as AI becomes more powerful,

Speaker 2 it's going to become more or less clear to everyone what the strategy should be. And it should be something like, Yeah, you need to find some way to talk to each other, and you want your first

Speaker 2 actual, like, real, super-intelligent AI to be aligned and somehow be

Speaker 2 you know care for sentient life care for people democratic one of those some combination of thereof and I think

Speaker 2 this is the condition

Speaker 2 that everyone should strive for

Speaker 2 and that's what SSI is striving for and I think

Speaker 2 that

Speaker 2 this time, if not already, all the other companies will realize they're striving towards the same thing. And we'll see.
I think that the world will truly change as AI becomes more powerful. Yeah.

Speaker 2 And I think a lot of these forecasts will, like,

Speaker 2 I think things will be really different and people will be acting really differently.

Speaker 1 What speaking of forecasts, what are your forecasts to this system you're describing, which can learn as well as a human

Speaker 1 and

Speaker 1 subsequently, as a result, become superhuman?

Speaker 2 I think like five to twenty.

Speaker 1 Five to twenty years?

Speaker 1 So I just want to unroll your

Speaker 1 how you might see the world coming it's like we have a couple more years where these other companies are continuing the current approach and it stalls out and stalls out here meaning they earn no more than low hundreds of billions in revenue or how do you think about what stalling out means yeah

Speaker 2 I think they're rev I think it could I think it could stall out and

Speaker 2 I think stalling out will look like

Speaker 2 it will all look very similar yeah among all the different companies, something like this. I'm not sure because

Speaker 2 I think even with Stolen Audio, I think these companies could make a

Speaker 2 stupendous revenue. Maybe not profits because

Speaker 2 they will need to work hard to differentiate each other from themselves, but revenue definitely.

Speaker 1 But

Speaker 1 something in your model implies that

Speaker 1 when the correct solution does emerge, there will be convergence between all the companies. And I'm curious why you think that's the case.

Speaker 2 Well, I was talking more about convergence on their largest strategies.

Speaker 2 I think eventual convergence on the technical approach is probably going to happen as well. But I was alluding to convergence to the largest strategies.

Speaker 2 What exactly is the thing that should be done?

Speaker 1 I just want to better understand how you see the future unrolling.

Speaker 1 So currently we have these different companies and you expect their approach to continue generating revenue, but not get to this human-like learner. Yes.

Speaker 1 So now we have these different forks of companies. We have you, we have thinking machines, there's a bunch of other labs.

Speaker 2 Yes.

Speaker 1 And maybe one of them figures out the correct approach.

Speaker 1 But then the release of their product makes it clear to other people how to do this thing.

Speaker 2 I think it won't be clear how to do it thing, but it will be clear that something different is possible. Right.
And that is information. And I think people will

Speaker 2 then be trying to figure out

Speaker 2 how that works. I do think, though, that one of the things that's that I think, you know, not addressed here, not discussed, is that

Speaker 2 with each increase in the AI's capabilities, I think there will be some kind of changes, but I don't know exactly which ones in how things are being done.

Speaker 1 And so like,

Speaker 2 I think it's going to be important, yet I can't spell out what that is exactly.

Speaker 1 And how are the

Speaker 1 By default, you would expect the company that has, the model company that has that model to be getting all these gains because they have the model that is learning how to do all,

Speaker 1 has the skills and knowledge that it's building up in the world what is a reason to think that the benefits of that would be widely distributed and not just end up at whatever model company gets this continuous learning loop going first

Speaker 2 like i think that empirically what happened so

Speaker 2 here here is what i think is going to happen number one i think empirically when

Speaker 2 let's look at let's look at how things have gone so far with um the ais of the past so one company produced an advance, and the other company scrambled and produced

Speaker 2 some similar things after some amount of time. And they started to compete in the market and

Speaker 2 push the prices down. And so, I think, from the market perspective, I think something similar will happen there as well.
Even if someone, okay, we are talking about the good world, by the way, where

Speaker 2 what's the good world?

Speaker 2 What's the good world?

Speaker 2 Where you have these powerful human-like learners that are also like, and by the way, maybe there's another thing we haven't discussed

Speaker 2 on the spec of the super intelligent AI that I think is worth considering, is that you make it narrow.

Speaker 2 Can be useful and narrow at the same time. So you can have lots of narrow super intelligent AIs.
But suppose you have many of them

Speaker 2 and

Speaker 2 you have some company that's producing a lot of profits from it, and then you have another company that comes in and starts to compete, and the way the competition is going to work is through specialization.

Speaker 2 I think what's going to happen is that

Speaker 2 the way

Speaker 2 competition, like competition loves specialization, and you see it in the market, you see it in evolution as well.

Speaker 2 So you're going to have lots of different niches, and you're going to have lots of different companies who are occupying different niches in

Speaker 2 this kind of world. But you might say, yeah, like one AI company is really quite a bit better at some area of really complicated economic activity.
And a different company is better at another area.

Speaker 2 And the third company is really good at litigation. And that's the lesson.

Speaker 1 This is contradicted by what human-like learning implies is that like it can learn.

Speaker 2 It can, but, but you have accumulated learning. You have a big investment.
You spent a lot of compute to become really, really, really good, really phenomenal at at this thing.

Speaker 2 And someone else spent a huge amount of compute and a huge amount of experience to get really, really good at some other thing.

Speaker 2 You apply a lot of human learning to get there. But now, like,

Speaker 2 you are at this

Speaker 2 high point where someone else would say, look, I don't want to start learning what you've learned today.

Speaker 1 I guess that would require many different companies to begin at the human continual learning agent at the same time, so that they can start their different research in different branches.

Speaker 1 But if one company

Speaker 1 gets that agent first or gets that learner first,

Speaker 1 it does then seem like, well,

Speaker 1 like if you just think about every single job in the economy,

Speaker 1 you just have

Speaker 1 instance learning each one seems tractable for companies.

Speaker 2 Yeah,

Speaker 2 that's a valid argument.

Speaker 2 My strong intuition is that it's not how it's going to go.

Speaker 2 My strong intuition is that, yeah, like the argument says it will go this way. Yeah.
But my strong intuition is that it will not go this way.

Speaker 2 That this is the

Speaker 2 you know, in theory, there is no difference between theory and practice, in practice, there is, and I think that's going to be one of those.

Speaker 1 A lot of people's models of recursive self-improvement literally explicitly state we will have a million Ilyas in a server that are coming in with different ideas, and this will lead to a super intelligence emerging very fast.

Speaker 1 Do you have some intuition about how parallelizable the thing you are doing is?

Speaker 1 How, how much, what are the gains from making copies of

Speaker 2 I don't know.

Speaker 2 I think there'll definitely

Speaker 2 be diminishing returns because you want people who think differently rather than the same. I think that if they were literal copies of me, I'm not sure how much more incremental value you'd get.

Speaker 2 I think that...

Speaker 2 But people who think differently, that's what you want.

Speaker 1 Why is it that it's been...

Speaker 1 If you look at different models, even released by totally different companies, trained on potentially non-overlapping data sets it's actually crazy how similar LLMs are to each other maybe the data sets are not as non-overlapping as it seems

Speaker 1 but

Speaker 1 there's there's some sense that it's like even if an individual human might be less productive than the future AI maybe there's something to the fact that human teams have more diversity than teams of AIs might have but how do we elicit meaningful diversity among AI?

Speaker 1 So I think just raising the temperature just results in gibberish. I think you want something more like different scientists have different prejudices or different ideas.

Speaker 1 How do you get that kind of diversity among AI agents?

Speaker 2 So, the reason there has been no diversity, I believe, is because of pre-training.

Speaker 2 All the pre-trained models are the same, pretty much, because they're pre-trained on the same data.

Speaker 2 Now, RL and post-training is where some differentiation starts to emerge because different people come up with different RL training. Yeah.

Speaker 1 And then I've heard you hint in the past about self-play as a way to either get data or match agents to other agents of equivalent intelligence to kick off learning. How should we think about

Speaker 1 why

Speaker 1 there's no public

Speaker 1 proposals of this kind of thing and working with LLMs?

Speaker 2 I would say there are two things to say. I would say that the reason why I thought self-play was interesting.

Speaker 2 is because it offered a way to create models using compute only without data. Right? And if you think that data is the ultimate bottleneck, then using compute only is very interesting.

Speaker 2 So that's what makes it interesting. Now,

Speaker 2 the thing is

Speaker 2 that self-play, at least the way it was done in the past, when you have agents which are somehow competing with each other, it's only good for developing a certain set of skills. It is too narrow.

Speaker 2 It's only good for like negotiation, conflict,

Speaker 2 certain social skills, strategizing, that kind of stuff. And so, if you care about those skills, then self-play will be useful.
Now, actually, I think that self-play

Speaker 2 did

Speaker 2 find a home, but just in a different form,

Speaker 2 in a different form. So, things like debate, prove a verifier, you have some kind of an LLM as a judge, which is also incentivized to find mistakes in your work.

Speaker 2 You could say this is not exactly self-play, but this is a related adversarial setup that people are doing, I believe. And really self-play is an example of,

Speaker 2 is a special case of more general, like

Speaker 2 competition between agents, right? The response, the natural response to competition is to try to be different.

Speaker 2 And so if you were to put multiple agents and you tell them, you know, you all need to work on some problem, and you are an agent, and you're inspecting what everyone else is working, you're going to say, well, if they're already taking this approach, it's not clear I should pursue it.

Speaker 2 I should pursue something differentiated. And so I think that something like this could also create an incentive for a diversity of approaches.

Speaker 1 Final question.

Speaker 1 What is research taste? You're obviously

Speaker 1 the person in the world who is considered to have the best taste in doing research in AI.

Speaker 2 You are

Speaker 1 the co-author on many of the biggest, the biggest things that have happened in the history of deep learning from AlexNet to GPT-3 to so on. What is it that, how do you characterize how

Speaker 1 you come up with these ideas?

Speaker 2 I can answer. So I can comment on this for myself.
I think different people do it differently.

Speaker 2 But one thing that

Speaker 2 guides me personally

Speaker 2 is

Speaker 2 an aesthetic of how AI should be

Speaker 2 by thinking about how people are, but thinking correctly.

Speaker 2 Like, it's very easy to think about how people are incorrectly. But what does it mean to think about people correctly? So I'll give you some examples.

Speaker 2 The idea of the artificial neuron is directly inspired by the brain. And it's a great idea.
Why? Because you say, sure, the brain has all these different organs.

Speaker 2 It has the faults, but the faults probably don't matter.

Speaker 2 Why do we think that the neurons matter? Because there is many of them. It kind of feels right.
So you want the neuron.

Speaker 2 You want some kind of local learning rule that will change the connections. You want some local learning rule that will change the connections between the neurons.

Speaker 2 Right? It feels plausible that the brain does it. The idea of the distributed representation,

Speaker 2 the idea that the brain,

Speaker 2 you know, the brain responds to experience, our neural net should learn from experience, not response. The brain learns from experience.

Speaker 2 The neural net should learn from experience. And you kind of ask yourself, is something fundamental or not fundamental? How things should be?

Speaker 2 And I think that's been guiding me a fair bit, kind of thinking from multiple angles and looking for almost beauty. Beauty, simplicity.
Ugliness, there's no room for ugliness.

Speaker 2 It's just beauty, simplicity, elegance, correct inspiration from the brain. And all of those things need to be present at the same time.

Speaker 2 And the more they are present, the more confident you can be in a top-down belief.

Speaker 2 And then the top-down belief is the thing that sustains you when the experiments contradict you. Because if you just trust the data all the time,

Speaker 2 well, sometimes you can be doing a correct thing, but there's a bug. But you don't know that there is a bug.
How can you tell that there is a bug?

Speaker 2 How do you know if you should keep debugging or you conclude it's the wrong direction? Well, it's the top-down. Well, how should you say the things have to be this way?

Speaker 2 Something like this has to work. Therefore, you got to keep going.
That's the top-down. And it's based on this like multifaceted beauty and inspiration by the brain.

Speaker 2 All right.

Speaker 1 We'll leave it there. Thank you so much.
Thank you so much.

Speaker 2 All right. Appreciate it.
That was great. Yeah.
I enjoyed it. Yes, me too.
